Substitute Part Grouping Explanation

Substitution of the VT1546MBFQR is determined by the following criteria:

• Base Product Number Match: The substitute part must share the VT1546 base product number, ensuring functional equivalence within the product family
• Manufacturer Consistency: Substitute parts must originate from Analog Devices Inc./Maxim Integrated to maintain design validation and supply chain reliability
• Category Alignment: Both parts must function as Power Management (PMIC) Switching Regulator IC Output components
• Compliance Requirements: RoHS3 compliance and REACH unaffected status must be maintained
• Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures equivalent handling and storage requirements

The VT1546MBFQX meets all substitution criteria as an active product variant within the same base product family.

Parameter Comparison

Engineering Selection Recommendations

The VT1546MBFQX is the manufacturer-recommended substitute for the obsolete VT1546MBFQR. Both parts maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected) and equivalent moisture sensitivity ratings. The VT1546MBFQX is currently in active production status with significantly higher inventory availability, ensuring supply chain continuity for new designs and production requirements. Selection of the VT1546MBFQX eliminates obsolescence risk while preserving functional and regulatory equivalence.
